Progress and Pitfalls in Cancer Survival
30 Jun
Summary
- Overall cancer survival rose from 49% to 69% between 1975 and 2020.
- Some cancers saw dramatic survival improvements, others stalled or declined.
- Racial disparities in survival rates have narrowed but persist significantly.
Cancer survival rates have demonstrated a notable, yet uneven, trajectory since 1975. Overall five-year survival has climbed from 49% to 69% as of 2020, a testament to medical advancements like targeted therapies and immunotherapies, alongside earlier detection methods.
Diseases such as leukemia, myeloma, and Non-Hodgkin lymphoma have seen survival rates more than double. However, this upward trend is not universal. Cancers like larynx, uterine corpus, and cervical cancer have experienced declines in survival rates over the same period, despite established screening protocols.
The gap in survival rates between Black and white patients has narrowed from 11 percentage points to 5, yet significant disparities remain, especially in breast cancer where the difference persists at 9 points. Ovarian cancer survival rates for Black women have unfortunately fallen below those of white women.
For particularly challenging cancers like pancreatic, liver, and esophageal cancer, survival rates remain low, hovering around 13% to 22%, indicating a critical need for further research and intervention. These statistics highlight the complex reality behind the overall survival figures.
